Brakes - Honda CRF450R Owner's Manual

Refer to Safety Precautions on page 19.
Both the front and rear brakes are the hydraulic
disc type. As the brake pads wear, the brake
fluid level will drop. A leak in the system will
also cause the level to drop.
Frequently inspect the system to ensure there are
no fluid leaks. Periodically inspect the brake
fluid level and the brake pads for wear.
If the front brake lever or rear brake pedal
freeplay does not feel within the normal range
while riding, check the brake pads. If they are
not worn beyond the recommended limit (page
82), there is probably air in the brake system.
Refer to the Honda Service Manual or see your
Honda dealer to have the air bled from the
system.
